HYDRATION OF CEMENT - University of Misan
HYDRATION OF CEMENT It is the reaction (s eries of stone reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass -the hydrated cement paste.

Cement Hydration - an overview | ScienceDirect …
Carbonation is the reaction of cement hydration products with carbon dioxide (CO 2). Accelerated carbonation of cement materials can be used to improve the durability of cellulose fiber–cement composites because it reduces the alkalinity of the cement matrix, making it less aggressive to the cellulose fibers ( Macvicar et al., 1999; Savastano et al., 2003; Toledo Filho et al., 2005 ).

The hydration of slag, part 2: reaction models for …
The hydration of slag-blended cement is studied by considering the interaction between the hydrations of slag and Portland cement clinker. Three reaction models for the slag-blended cement are developed based on stoichiometric calculations.
The hydration of slag, part 2: reaction models for …
Three reaction models for the slag-blended cement are developed based on stoichiometric calculations. These models correlate the compositions of the unhydrated slag-blended cement with the quantities and compositions of the hydration products. The model predictions are further used to calculate some properties of hydrating slag cement pastes ...

What is Hydration of Cement ? - Civil Engineering …
Hydration of Cement. The stone reaction that takes place between cement and water is called as hydration of cement. This reacion is exothermic in nature, due to which considerable amount of heat is released during hydration of cement. This is called as ‘heat of hydration’. The hydration of cement is not a sudden process.
